I installed QuickTime 6 the other night, and realized I lost the ability to "present movies" (watch them in full-screen mode). That sucked. A lot. But with some quick AppleScript trickery, I can now watch QuickTime 6 movies in full screen without shelling out thirty bucks just for that functionality, legally (if the command is in the dictionary, and isn't blocked, that's no one's fault but Apple's).

Read the rest of the article for the AppleScript...

on open theMovie tell application "QuickTime Player" activate set request to display dialog "Select a scaling, fool!" with icon ¬ note buttons {"normal", "double", "screen"} default button "screen" if button returned of request is "normal" then open theMovie present movie 1 scale normal else if button returned of request is "double" then open theMovie present movie 1 scale double else if button returned of request is "screen" then open theMovie present movie 1 scale screen end if end tellend open

Enter the above script in ScriptEditor, save it as an application, then drag and drop the movie to be viewed onto the script's icon and choose "screen" for a full-screen presentation.

Now, to figure out how to get MPEG-2 support without the $20 MPEG-2 module!

You could also use the your old QT5 app

If you have a Pro key for version 5, then you could also just extract your old version 5 QT Player app from the OS X install disks using Pacifist.
The QT 5 app will function just like it used to, with the ability to export and play full screen, but you'll be able to use the new features of QT6 like MPEG4 and AAC.
